Calibration of DMSTA Storage Parameters

6/7/2002

Model Parameters:

PSTA & EMERGENT

SAV

C0  =

Water Column Conc at Storage = 0 mg/m2

4

12

C1 =

Water Column Conc at Storage = 1000 mg/m2

22

22

C0 ~ Minimum Achievable Water Column Concentration in a Steady-State, Constant-Flow System

Estimation from Concentration vs. Storage Relationship:

Intercept =

C0

Slope =

1000 / (C1 - C0)

Calibrated Using Biomass & P Conc. Data from "Aged" (Post Startup) Systems

Assumptions:

Biomass is Fully Developed (~at Steady State with Ambient P Concentration)

Stored P Includes Periphyton, Above-Ground & Below Ground Macrophytes, Live & Dead, Organic & Inorganic

Stored P Does Not Include not Include Litter, Floc, or Soils

Alternative Calibrations

A

C0=4,  C1=22

PSTA & Emergent Systems

B

C0=12,  C1=22

SAV Systems; C0 adjusted based upon residuals from concentration simulations
